1. Application |
| |
DZ65-63 is applicable to a line of AC 50Hz/60Hz, 230V in single pole, 400V in double, three,four poles for protecting overload and short circuit, and rated current up to 63A. It can also beused for infrequent line conversion under the normal condition.The breaker is applicable to light-ing distribution system in industrial enterprise, commercially district, high-rise building and dwell-ing house. It conforms with the standards of IEC60898.
